Meanings of constitutive models in English

Biological tissues exhibit complex mechanical behaviors not easily accounted for in classic elastomeric constitutive models.

Here we considered phenomenological and microstructurally motivated constitutive models and identified material parameters for each via nonlinear regression.

The present study also underscores the need for rigorous experimentation and accurate constitutive models in simulating BHV function and design.

By further measuring deformation, we obtain a pressure-stretch relationship that is used to identify constitutive models of the zebrafish embryonic cardiac tissue.

Accounting for these behaviors by careful experimental evaluation and formulation of constitutive models continues to be a challenging area in biomechanical modeling and simulation.

A method of addressing this issue is to implement computationally expensive finite element models, characterized by precise constitutive models including high-order and high-density mesh techniques.
